RX 580 frame rate drops in Ryzen 1600

[amarflybot]

Hi Guys,
I have recently installed macOs with Opencore 0.6.0.

System config:
Ryzen 1600 + Gigabyte GA-AB350N-Gaming WIFI (rev. 1.0) + RX 580
Everyting works well except the graphics card.
The cinebench score I get is 2595.

The only issue is with Unigine Heaven and Valley. The get only 31 FPS avg. Whereas the same machine dual boot on windows gives me 80-90 fps.

Could you please let me know what am I missing?
Uploaded the config.plist file. Please help!!

你好，可以尝试在显卡驱动里手动添加Opencore 0.6.0程序，并根据个人喜好设置或系统推荐设置，完成后运行Opencore 0.6.0
